dataClass.new( )
dataClass.new( )
The dataClass.new( ) method creates in memory and returns a new blank entity related to the dataClass.
The entity object is created in memory and is not saved in the database until the entity.save( ) method is called. If the entity is deleted before being saved, it cannot be recovered.
4D Server: In client-server, if the primary key of the corresponding table is auto-incremented, it will be calculated when the entity is saved on the server.
This example creates a new entity in the "Log" dataClass and records information in the info attribute:
C_OBJECT($entity)
$entity:=ds.Log.new() //create a reference
$entity.info:="New entry" //store some information
$entity.save() //save the entity
